GRAIN GUARD f Filed Jan.' 27', 1940 Patented Nov. 4, 1941 UNITED STATES PATENT OFFICE GRAIN GUARD Hubert E. Kanchl, Solomon, Kans. Application January 27, 1940, Serial No. 315,987

6 Claims.

This invention relates to improvements in grain guards for combines, binders, headers, and the like.

It is an object of the invention to provide a guard of flexible construction which may be readily attached to the ordinary guard forming a part of agricultural machines of the types mentioned.

A further object of the invention resides in providing a device of the above-mentioned character which is simple and durable in construction, reliable and efficient in operation, and inexpensive to manufacture.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a perspective view of the improved guard,

Fig. 2 is a horizontal section taken on line 2-2 of Fig. 1,

Fig. 3 is a vertical section taken on line 3-3 of Fig. 1', and

Fig. 4 is a perspective view of the attaching bracket and adjusting loop.

In the drawing, wherein for the purpose of illustration I have shown a preferred embodiment of my invention, the numeral 5 denotes generally an ordinary guard which forms a part of a combine, binder, or reaper.

Referring more particularly to my invention,`a supporting bracket 6 formed of channel iron is attached to the ordinary guard 5 and extends longitudinally therefrom. The guard is disposed in the channel of the bracket, the botto-m of the channel being slotted, as at l, to allow for adjustment of the bracket and a loop 8 encircles the bracket and guard and is held in its adjusted position by the protuberances 9 on the bottom of the bracket. The sides of the bracket at one end are bent laterally to provide outwardly extending lugs III for attaching the bracket rmly in place. A ground shoe II which is T-shape in cross section has one end pivotally connected to the outer end of the bracket 6 by side plates I 2 which are xedly attached to the shoe by rivets I3 and the upper ends of the plates are OIT-set outwardly as at I4, forming shoulders to receive the bracket and a pivot pin I5 hingedly connects the plates to the bracket to permit vertical swinging movement of the ground shoe. The forward end of the ground shoe is curved upwardly, as at I6, and is, pivotally connected to the forwardend of the spaced parallel grain bars I'I by a pin I3. The barsj Il extendrearwardly in an upwardly inclined direction, being supported by a link bar F9 pivotally connected at one end to the bars I1, as at 20, and having its opposite end connected to the forward end of the bracket 6 by a pivot 2 I. A coil spring 22 extends between the inner end of the ground shoe I I and rear end of the bracket 6 which tends to return the ground shoe to its normal position when swung upwardly.

In operation, the grain guard is freely movable in a vertical direction which allows flexibility in performing its function and prevents breakage. The ground shoe II is capable of vertical swinging movement by reason of its pivotal connection at its inner end with the bracket 6 and when raised upwardly the bars Il which are pivotally connected at one end to the forward end of the ground shoe move rearwardly and swing the pivoted link bar I9 backwardly. By reason of this construction when the bars Il move rearwardly their inner ends are raised upwardly by the link bar I9. It may be readily attached to an ordinary guard and is adjustable to fit guards of different lengths.

I-t is to be understood that the form of my invention herein shown and described is to be taken as a preferred example of the same.. and thatcertain changes in the shape, size, and arrangement of the parts may be made without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim:

1. A grain guard comprising a supporting bracket, a ground shoe pivotally connected to the outer end of said bracket and extending longitudinally therefrom, grain bars pivotally connectedat one end to the outer end of said ground shoe and extending rearwardly in an upwardly inclined direction, and a link bar pivotally connecting said grain bars to said bracket.

2. A grain guard comprising a supporting bracket of channel construction adapted to engage an ordinary guard, means adjustably securing said bracket to the ordinary guard, a ground shoe pivotally attached to said bracket, for vertical swinging movement, grain bars connected to the forward end of said ground shoe and extending rearwardly therefrom in an upwardly inclined direction, and a link bar pivotally connecting the free ends of said grain bars to said bracket.

3. A grain guard comprising a supporting bracket for attachment to an ordinary guard, a ground shoe. side plates attached to the rear end of said shoe, said plates having their upper ends offset to provide a seat to receive said supporting bracket, a pivot pin pivotally connecting said side plates to said bracket to permit vertical swinging movement of said ground shoe, and grain bars pivotally connected to the forward end of said ground shoe and extending rearwardly therefrom in an upwardly inclined direction.

4. A grain guard comprising a supporting bracket for attachment to an ordinary guard, a ground shoe, side plates pivotally connecting the rear end of said shoe to the forward end of said bracket to permit Vertical movement of said shoe, grain bars pivotally connected to the forward end of said ground shoe and extending rearwardly therefrom in an upwardly inclined direction, a link bar pivotally connecting the free ends of said grain bars with said supporting bracket, and a spring extending between the rear end of said ground shoe and the rear end of said bracket to normally hold said shoe in engagement with the ground.

5. A grain guard comprising an attaching bracket, a ground shoe, a U-shaped bracket fixedly secured to the inner end of said ground shoe to receive said attaching bracket, a pivot pin pivotally connecting said U-shaped bracket to said attaching bracket to permit upward swinging movement of said ground shoe, said U-shaped bracket having shoulders along its inner walls adapted to contact with the attaching bracket and limit its dowward movement, and a grain bar extending rearwardly and upwardly from. the forward end of said ground shoe.

6. A grain guard comprising an attaching bracket, a ground shoe having its inner end pivotally connected to said attaching bracket to permit vertical swinging movement of said ground shoe, grain bars pivotally connected at one end to the forward end of said ground shoe and extending rearwardly therefrom, and a forwardly inclined link bar having one end pivotally connected to said attaching bracket and its opposite end pivotally connected to said grain bars adjacent their free ends.
